September 29, 2025, Singapore – Cypherock, the pioneering self-custody solution behind the industry-leading Cypherock X1 hardware wallet, today announced a strategic integration with Changelly, a leading instant exchange platform and the most trusted blockchain API provider. This collaboration introduces the safest way to perform crypto swaps directly from cold storage, setting a new benchmark in convenience and security for global users.
A milestone in secure crypto swaps
Swapping cryptocurrencies has long been a balancing act between security, convenience, and cost-efficiency. Most traders and holders have been forced to either rely on centralized exchanges, risking custody of their assets, or use hot wallets that expose them to online attack vectors.
By integrating Changelly’s robust and secure exchange infrastructure with Cypherock’s sharded cold storage architecture, users can now initiate trustless, secure swaps directly from their hardware wallet without ever compromising private keys or exposing assets to third-party custody.
This means:
No centralized risk: Users retain full control of their keys at all times.
Hardware-level protection: Swaps are initiated and signed in the Cypherock X1, ensuring maximum resistance against hacks or malware much more safer than existing hardware wallets.
Seamless user experience: Cypherock’s cySync app provides a smooth and intuitive swap interface powered by Changelly’s liquidity and exchange engine. (Swaps are currently available via the desktop version of cySync.)
Cypherock X1: Security beyond standards
The Cypherock X1 isn’t just another hardware wallet - it is designed for uncompromising safety and future-proof sovereignty. Some of its standout features include:
Open-source, audited, and verified reproducible firmware, ensuring transparency and verifiability of its security claims.
Non-custodial inheritance feature that supports multi-token and multi-chain assets, unlike most inheritance solutions today that are limited to Bitcoin only.
Seedphrase vulnerability free architecture, using Shamir Secret Sharing (SSS), eliminating single points of failure common in traditional hardware wallets.
Dual platform compatibility through cySync mobile and desktop apps, giving users flexibility in managing assets across environments.
With these innovations, Cypherock sets a new benchmark in secure self-custody for individuals and families, ensuring that assets remain protected not just during the user’s lifetime but also for generations to come.
Why this matters for Web3 self-custody
The partnership addresses one of the biggest gaps in the crypto ecosystem: enabling users to stay sovereign while still accessing liquidity and asset diversification tools.
"At Cypherock, our mission is to empower users to truly own and control their crypto assets without compromise. By integrating Changelly, we’ve eliminated the trade-off between security and convenience in swaps. Users can now diversify their portfolios directly from the safety of their cold storage," said Akhil Jonnavithula, Director of Business Development at Cypherock.
Changelly, which has been providing crypto swaps and purchases to over 10 million users since 2015, brings its unmatched reputation and liquidity network to the partnership.
"This integration reflects our shared vision of making crypto more secure and accessible. By joining forces with Cypherock, we’re enabling users to experience Changelly’s seamless swaps backed by the highest level of security," said Nik Kos, Head of Partnerships at Changelly.
Redefining the future of crypto utility
With this launch, Cypherock moves one step closer to its vision of becoming the most secure and versatile self-custody platform. The collaboration not only empowers Bitcoin and Ethereum users, but also supports a wide range of digital assets available through Changelly’s liquidity network.
This integration is particularly relevant in today’s environment, where self-custody adoption has accelerated post-FTX and other exchange failures. Users are increasingly prioritizing safety without wanting to sacrifice usability, and the Cypherock-Changelly collaboration solves precisely that pain point.
